I don't use javascript, I use jquery....well I know it does not make sense, but I just want to stress how important it is. let's rephase it: whenever I use javascript, I use jquery. when you look at any js file of mine, 90% is jqery api.

jQuery has it's quirks, but they're well understood. We opted for a more traditional web app using older, more well-tested technologies like jQuery instead of newer "single page application" type apps.

jQuery is only used in small amounts, primarily for animations and UIs, but it is included in the WSC, so we felt like not including it here would be kind of cheating. jQuery also almost makes ajax-requests a pleasure to work with, so ... you got that point, jQuery.

jQuery has been the basis of our front end JS for a number of years. The key part for us was that the amount of code saved by using jQuery methods, as opposed to writing out cross-browser compatible alternatives made it a no brainer. In recent years we've had to be clever in how we deliver jQuery on the websites, to ensure it's not render blocking and improve client-side performance but it's still a vital library.
